Symptom: P0123-THROTTLE POSITION SENSOR #1 VOLTAGE TOO HIGH When Monitored and Set Condition: P0123-THROTTLE POSITION SENSOR #1 VOLTAGE TOO HIGH When Monitored: With the ignition on and battery voltage above 10.4 volts. Set Condition: Throttle Position Sensor signal voltage at the PCM goes above 4.5 volts for 3.2 seconds. POSSIBLE CAUSES TP SENSOR SWEEP INTERMITTENT CONDITION TP SENSOR (K22) TP SENSOR NO.1 SIGNAL CIRCUIT SHORTED TO VOLTAGE (K22) TP SENSOR NO.1 SIGNAL CIRCUIT OPEN (K22) TP SENSOR NO.1 SIGNAL CIRCUIT SHORTED TO (K7) 5-VOLT SUPPLY CIRCUIT (K900) SENSOR GROUND CIRCUIT OPEN PCM TEST ACTION APPLICABILITY 1 Ignition on, engine not running. t, read DTCs and record the related Freeze Frame data. NOTE: Ensure the throttle is fully closed and free from binding or carbon t, read the Throttle Position Sensor voltage. Is the voltage above 4.5 volts? All Yes → Go To 2 No → Go To 8 2 Turn the ignition off. t, monitor the TP Sensor voltage. Is the voltage below 0.5 of a volt? All Yes → Replace the Throttle Position Sensor. Perform POWERTRAIN VERIFICATION TEST VER - 5. No → Go To 3 NOTE: Remove the jumper wire before continuing. 51 DRIVEABILITY - GAS |
